Allegations of child sexual abuse have considerable consequences for individuals and society. Herein, we report 2 cases of false allegations of child sexual abuse by mothers diagnosed as paranoid disorder. Case 1, a 31-year-old mother accused her husband of sexually abusing her 3 daughters, aged 2, 4, and 6 years. Case 2 is a 30-year-old mother that went to the public prosecutor with allegations of sexual abuse of her 6-year-old daughter by a nursery teacher and a stranger. Examination of both alleged victims did not reveal objective findings of sexual abuse. Based on psychiatric examinations, both mothers were diagnosed with paranoid disorder. Consequently, the public prosecutor decided not to prosecute. Considering the possibility of false allegations in such cases, psychiatric examination of the complainant should be performed in order to provide accurate information necessary for legal proceedings and to protect the child.
